I plan to use a concrete pad that will serve as a deck as well as the roof for the room below. Is it best to waterproof the concrete by pouring a couple of inches, installing a membrane and then pouring the other 2-3 inches of concrete? Does anyone know a better way? Thank you for any information or comments.

Pouring two layers is a recipe for disaster... Water will get through the surface layer and pond on the membrane...when it freezes it will break the upper layer. Look into Grailcoat or similar coatings. Grailcoat is a traffic durable coating that is also waterproof. You would apply the Grailcoat on the top surface of the concrete deck. The Grailcoat is also flexible enough to bridge over different substrates. Check out the website that appears in the banner ads on this site.

We are currently installing an aluminum interlocking waterproof deck made by www.lockdry.com
We are still installing so we don't have final comments yet.

Try Xypex, it may be what you are looking for.

My take on using Xypex is that it wouldn't perform adequately for a deck. Xypex is a good admix, but it wouldn't perform well as a traffic surface. Also, Xypex works on the premise that water must get to it in order to crystalize....If the deck has cracks either caused by shrinkage, thermal or structural, then water will first leak through possibly causing some damage or mold prior to the Xypex actually sealing the leak....Correct me if I am wrong please

Would like to thank all of you for your response. Perhaps the best approach may be to use the Xypex treatment and Grailcoat assuming there are no compatibility issues.
I would think the concrete formulation would also be very important, to minimize porosity and tendency to crack.

Thank you,
Dub

i've seen this type thing before on some of the builder/remodelers tv programs. you might try contacting some of the web sites such as HGTV.com. you might also contact the major concrete manufacturers to see what they suggest. you cant be the first and only person to want to do a project like this. good luck.

they make a range of liquid membrane products for all types of applications, including flexible non-slip.
